Great diving. Great food. Brilliant adventure

Diving was brilliant. Cocos Island is cool, so many waterfalls. The diving was really well organised, the staff on the boat worked really hard. We were worried about the food, as my husband has Coeliacs, but the attention to detail on this was superb, they brought out gluten free options whenever required. Also the staff at Liveaboard.com were great, they jumped straight onto a mix up with my booking, it was really easy to get hold of them on the phone, and the mix up was sorted straight away.

Perfect sport for shark lovers

Cocos Island is a fantastic option for shark lovers due to the variety you can find at each dive. It is a long trip from Costa Rica but completely worth it. The crew did a great job to make sure we all felt comfortable. Special mention to the chef and his assistant, who amazed us every day with fantastic dinners.

Enchanting island teeming with under the sea life...amazing!

Seeing a Manta Ray, hammerheads, marble rays, spotted eagle rays, a Galapagos shark and the whale shark on Easter morning first dive of the day with dolphins playing in the water when we boarded the panga. Yes, all of this on one dive...spectacular!
